Abstract

A device ( 1 ) includes a body ( 2 ) and a touch panel ( 3 ) supported by, integrated with, or underlying the body ( 2 ). The touch panel ( 3 ) includes a layer of piezoelectric material ( 5 ) disposed between a plurality of first electrodes ( 6 ) and at least one second electrode ( 7 ). The device ( 1 ) also includes at least one second piezoelectric input region ( 8 ) supported by, integrated with, or underlying a portion of the body ( 2 ) which does not correspond to the touch panel ( 3 ). The device ( 1 ) is configured to receive user input using the touch panel ( 3 ) and/or at least one piezoelectric input region ( 8 ).

Claims (32)

1. A device comprising:

a body having a principal surface and one or more second surfaces, the one or more second surfaces comprising:

a rear surface opposing the principal surface across the body; and

one or more side surfaces, each side surface adjoined to the principal surface by a respective connecting edge, and connecting the principal surface to the rear surface, wherein the one or more connecting edges extend around the perimeter of the principal surface;

a touch panel configured on the principal surface of the body, the touch panel comprising a layer of piezoelectric material disposed between a plurality of first electrodes and at least one second electrode, wherein the layer of piezoelectric material comprises a net which is folded to conform to at least a shape of a part of the body; and,

at least one second piezoelectric input region, each at least one second piezoelectric input region comprising an extension of the layer of piezoelectric material and configured on one of the one or more second surfaces of the body,

wherein the device is configured to receive user input using the touch panel and/or the at least one second piezoelectric input region.

2. The device according to claim 1 , wherein the at least one second piezoelectric input region is configured on the principal surface of the body.

3. The device according to claim 1 , wherein the at least one second piezoelectric input region comprises one or more third electrodes configured to provide force sensitive buttons.

4. The device according to claim 1 , wherein the at least one second piezoelectric input region comprises a plurality of third electrodes configured to provide one or more slider controls.

5. The device according to claim 1 , wherein the touch panel is substantially rectangular.

6. The device according to claim 5 , wherein the device and the at least one second piezoelectric input region are configured to receive input in the form of a swiping movement.

7. The device according to claim 1 , wherein the touch panel is substantially circular.

8. The device according to claim 7 , wherein the device and the at least one second piezoelectric input region are configured to receive input in the form of a twisting movement about the substantially circular touchscreen.

9. The device according to claim 7 , wherein the device and the at least one second piezoelectric input region are configured to receive input in the form of a swiping movement.

10. The device according to claim 1 , wherein the device is a portable communications device.

11. The device according to claim 1 , wherein the device is a smart watch.

12. The device according to claim 1 , wherein the device is a mobile phone.

13. The device according to claim 1 , wherein the touch panel and the at least one second piezoelectric input region are operative to receive input using a combination of piezoelectric signals and capacitive sensing.

14. The device according to claim 1 , wherein the device is a peripheral for a computing device.

15. The device according to claim 14 wherein the touch panel and the at least one second piezoelectric input region are operative to receive input using a combination of piezoelectric signals and capacitive sensing.

16. The device of claim 1 wherein the at least one second piezoelectric input region is configured on at least one of the one or more side surfaces.

17. The device of claim 1 wherein the at least one second piezoelectric input region is configured on the rear surface.

18. The device of claim 1 , wherein the connecting edges are curved between the principal surface and each side surface of the one or more side surfaces.

19. A device comprising:

a body having a principal surface and one or more second surfaces, the one or more second surfaces comprising:

a rear surface opposing the principal surface across the body; and

one or more side surfaces, each side surface adjoined to the principal surface by a respective connecting edge, and connecting the principal surface to the rear surface, wherein the one or more connecting edges extend around the perimeter of the principal surface;

a touch panel configured on the principal surface of the body, the touch panel comprising a layer of piezoelectric material disposed between a plurality of first electrodes and at least one second electrode; and,

at least one second piezoelectric input region, each second piezoelectric input region configured on one of the one or more second surfaces of the body,

wherein the device is configured to receive user input using the touch panel and/or the at least one second piezoelectric input region.

20. The device of claim 19 , wherein the connecting edges are curved between the principal surface and each side surface of the one or more side surfaces.
